Remove unused Usings across entire assembly

Question

I am wondering if maybe ReSharper is able to run through every class and remove unused usings? I looked but I don't see an option like this in R# 4.5. Has anyone seen this in Resharper outside of just being able to remove usings in a single class?

Answer 1

I believe that cleanup across a project is a new feature in ReSharper 5.

I take that back, the feature is in ReSharper 4.5. If you right click on the solution, there's a Cleanup Code... item, which allows you to apply a cleanup profile to the solution. You can create a new cleanup profile from the Code Cleanup node within ReSharper options, if you want a profile to just adjust the using directives.
